Getting Started With Arduino
The Arduino is an Open-Source single-board microcontroller platform designed to be cheap and easy to use. For this reason, it has become extremely popular with the DIY community. It’s pretty cool, and not just for microcontroller noobs. The nice thing about the Arduino platform is that all of the boring work is already done. You can just use your imagination and build interesting things without needing to worry about board design and sourcing parts. If you require more, everything is open source and you can extend the platform as desired.
There are several official Arduino boards available each with different size and features and many non-official designs. The Arduino boards generally composed of an Atmel 8-bit microcontroller with the peripheral components necessary to support communication with external circuitry. An interesting feature of the Arduino boards is the standard connector footprint that is used to allow the microcontroller board to be connected to expansion modules called Shields, footprint compatible expansion PCBs that can be stacked to provide extra I/O, motor control, memory, etc. As the system is open source, anyone can freely design their own microcontroller board, shields or any other connecting components.

The Arduino platform has its own cross-platform development environment. It was designed to be easy for those new to programming. Arduino programs are written in C or C++. Users only need to define a
loop() functions to make a runnable cyclic executive program. The setup function is run once, on application startup and is used to configure the board settings. The loop function is run repeatedly for the remainder of the operation of the board. Before a program is uploaded to the device, the IDE does some extra processing to the file adding an include header and a simple main() function. The source code for the IDE is available and released under the GNU General Public License, version 2.
